~0~:~~~~
In the following the invention will be explained in greater detail by a description of exemplified embodiments with reference to the drawings, wherein:
Fig. 7 to 5 show diagrammatic sectional views of various embodiments of a connection element according to the invention.
The connection element according to Fig. 'I comprises a sleeve insert 3 consisting of a flange-shaped sleeve head 1 and a tubular part 2, wherein the tubular part 2 is provided with an external thread 4 for fastening it to one end of a rod of a three-dimensional framework. A bolt 5 ,is guided through a through-bore of the sleeve insert 3, the head 6 of the bolts 5 resting on the end wall of the tubular part 2.
The bolt 5 has an elongate, smooth, round part 7 of the length Lg, a guide part 8 of the length Lf, the cross-section of which' may be polygonal, and an end part 9 of the length Le, which is provided with an external thread for fastening the connection element to a junction part of the three-dimensional framework.
To simplify the drawing, the junction part 90 and 'the rod 11 are indicated only by broken lines. In particular, the length Lg may be~ greater than the total of the lengths Lf and Le.
The bolt 5 is guided through the through-bare of a guide sleeve 12, from which the end part 9 projects. At the front part of the guide sleeve ~2 this through-bore is shaped complementally to the guide part 8 of the threaded bolt 5, so that a rotary movement of the guide sleeve 12 can be transmitted to the bolt 5 with as little play as possible.
The through-bore of the front part of the guide sleeve 12 can, therefore, also be polygonal; the same as the guided part of the _8_ ~(~~~fl~
bolt 5. Preferably these cross-sections are hexagonal. In contrast thereto the through-bore has in the rear part of the guide sleeve 12 a preferably round cross-section, in which case there occurs between the round part T of the bolt 5 and the preferably cylindrical inside wall of the guide sleeve 12 a relatively large gap, to form an open space in which a coil spring 13 can be accommodated. At the end of the rear part of the guide sleeve 12, preferably in the gap, an annular disk 14 is arranged and connected to it.
In the shell of the guide sleeve 12 an elongated opening 15 is provided, through which a pin can be loosely inserted and connected to the bolt 5, preferably radially in its guide part 8.
The spring 13 is arranged in the gap in such a way that at its one end it rests on the annular disk 14 and at its other end it rests on the pin 16 to press it forward and thereby push the end part 9 out of the guide sleeve 12, when it is, for example, pushed by hand into the guide sleeve 12. The transmitting of the rotary movement is ensured by the shape of the front part of the guide sleeve 12. On the other hand the pin 16 is provided so that the bolt 5 can be pushed with the fingers along the elongated opening 15 against the action of the spring 13.
The embodiment according to Fig. 1 has the property that the spring 13 remains clamped in the sleeve 12 when this is closed off by the disk 14, e.g. by cementing or welding. It then, therefore, is no longer easy to remove the spring 13 from the sleeve 12. This property is sometimes desirable so that the spring 13 will not get lost. Besides this advantage, the connection element according to Fig. 1 has the disadvantage that the bolt 5 is relatively long. This can be a considerable disadvantage and can be avoided by a round recess 17 on the face of the sleeve head 9. The circumference of this recess 17 must be slightly larger than the circumference of the guide sleeve 12, which on the outside may, for example, have a polygonal cross-section. On the periphery of the sleeve head °1 a recess 18 is provided so that, with the aid of a tool, the sleeve insert 3 can be screwed onto the end of the rod 1'1.
The connection element according to Fig. 2 corresponds essentially to that of Fig. 1, wherein for identical parts the same reference numerals were used: The sleeve 19 according to Fig. 2 has only a small round opening 20, so that after assembling the guide sleeve ~f9 a countersunk pin 21 can be fastened on the bolt 5. Such a design is often preferred when for aesthetic reasons the visible pin is to be dispensed with.
Naturally, in such a case that play between the head of the pin 29 and the round inside wall of the guide sleeve '99 is quite large. As the diameter of the coil spring 13 is well defined and smaller than the projecting part of the pin 21, no slipping of the spring '13 over the head of the pin 2'1 can take place. The diameter of the opening 20 must be slightly larger than the diameter of the pin 29 so that the latter can be pulled out. If need be the opening 20 can be dispensed with, e.g. when the ring '14 is fastened in the sleeve 19 after assembling the spring 13 and the bolt 5.
The connection element according to Fig. 3 corresponds essentially to that of Fig. 'I, and also here the same reference numerals were used for identical parts. With this design the bolt has a radial groove,. which is positioned in the plane perpendicular to the longitudinal axis of the bolt at least approximately in the. area between the smooth part 7 and the guide _5_ part 8. An open annular spring 22 is placed in this groove, the outside diameter of which spring is slightly smaller than the inside diameter of the rear part of a guide sleeve 23, but larger than the diameter of the smooth part 7. The thickness of 'the annular spring 22 may, for example, be smaller than the diameter of the pins 16 or 29 according to Fig. 1 and 2, respectively. In this case the guide sleeve 23 does not have an opening. With this type it is necessary, however, to provide a detachable annular disk which may, for example, be an annular spring that can be clamped into a groove at the end of the sleeve 23.
At the rear end the sleeve 23 has two diametrically opposed openings 26, 27, i.e. in the area where the groove is positioned into which the annular spring 24 can be clamped., so that the latter can be pulled out with the aid of tongues. The openings 26, 27 may be slightly shorter than the height of the recess 17 of the sleeve head 9, so that in the assembled state they remain hidden there. With this type the spring 25 is pressed between the annular springs 22 and 24. The open annular spring 24 could also be used in the connection element according to Fig. 1.
The connection element according to Fig. 4 corresponds to another variant of the type of Fig. 1, wherein for identical parts the same reference numerals were used. In this case, besides the head 6, the bolt comprises only two parts 7 and 9, and the sleeve insert 3 may be with or without a recess 17 tFig. 9). Between the part 9 and the guide sleeve 12, a guide insert 28 is inserted, which has an internal thread and on the outside is shaped complementally to the front part of the through-bore of the guide sleeve '92.
_g_ The through-bore of the front part of the guide sleeve 12 may therefore, also be polygonal, the same as the guided part of the guide insert 28. Preferably, these cross-sections are hexagonal.
In contrast thereto, in the rear part of the guide sleeve 12 the through-bore has a larger, preferably round cross-section, in which case there occurs between the round part 7 of the bolt and the preferably cylindrical inside wall of the guide sleeve 12 a relatively large gap, larger than with the type according to Fig.
1, to form a space in which a conical spring 29 can be accommodated, the diameter of which at the front is smaller than at the rear, so that at the front it presses against the guide insert 28 and at the rear against an annular disk 30 arranged on the end of the guide sleeve 12, the through-bore of which has the same cross-sectional shape and/or is slightly larger than the guide insert 28, so that the latter can be put in through this through-bore. In this case it is easier, after removing the bolt, to take out the spring 29 by pulling and turning it.
The connection element according to Fig. 5 corresponds essentially to the type of Fig, 1, wherein for identical parts the same reference numerals were used. However, with this type at the rear end of the guide sleeve 12 an at least approximately bell-shaped flange ring 31 is provided, which delimits an inside space which is dimensioned such that the head 1 of the sleeve insert 3 can be accommodated therein.
With the embodiment according to Fig. 5 the bell-shaped flange ring 31 is separate from the actual guide sleeve 12, and a bush 32 is provided to fasten the flange ring 31 to the guide sleeve 12, e.g. by screwing or by a bayonet connection. In this case the flange ring 31, the bush 32 and the guide sleeve 12 form a guiding device for the connection element.
The type according to Fig. 5 has the property that the spring no longer remains constantly clamped-in in the sleeve 12, if this is closed off by the bush 32, e.g. by screwing on. The spring 13 can, therefore, easily be removed from the sleeve 12. This property is often desirable so that the spring 13 can be replaced more easily. In addition to this advantage, the connection element of Fig. 5 has the further advantage that due to the bell-shaped flange ring 31 a well matching transition can be realized between the rod 11 and the guide sleeve 12. This type can be made without any opening whatsoever in the shell of the guide sleeve 12, as it can be dismantled very easily.
Instead of the pin 16, a projection of the bolt in the parts 7 and/or 8 may be provided, in which case the opening 15 may also be provided right up to the rear end of the guide sleeve 12.
In a further development of the invention the flange ring 31 may form an integral part with the rear end of the guide sleeve 12.
According to a further development of the invention the flange ring 31 could form an integral part with the bush 28.
In a further embodiment of the invention the bush 32 can fall away and the flange ring 31 may have a wall with a through-bore, the diameter of which is slightly larger than the maximum diameter of the bolt 5.
Finally, the outside of the flange ring 31 may be conical to adapt the larger circumference of the rod 11 to the smaller circumference of the guide sleeve 12.
With the exception of the springs, the other parts may be made from aluminium or another light metal alloy.
_8_ 2~~~~~~
The flange rang 31 and, if it forms an integral part of the sleeve 12 (fig. 5), also the latter may be made from plastic.
The variants of a sleeve with a flange ring explained in connection with Fig. 5 can also be used for other type connection elements.
Finally, it must still be pointed out that instead of a coil spring it is also possible to use a spring that is put on from the side, e.g. a meander-shaped spring, and that with a view to maintaining the tolerances the flange ring andtor the sleeve may also be made from die cast metal, e.g. as bronze or zinc die castings.
_g_
In the following the invention will be explained in greater detail by a description of exemplified embodiments with reference to the drawings, wherein:
Fig. 7 to 5 show diagrammatic sectional views of various embodiments of a connection element according to the invention.
The connection element according to Fig. 'I comprises a sleeve insert 3 consisting of a flange-shaped sleeve head 1 and a tubular part 2, wherein the tubular part 2 is provided with an external thread 4 for fastening it to one end of a rod of a three-dimensional framework. A bolt 5 ,is guided through a through-bore of the sleeve insert 3, the head 6 of the bolts 5 resting on the end wall of the tubular part 2.
The bolt 5 has an elongate, smooth, round part 7 of the length Lg, a guide part 8 of the length Lf, the cross-section of which' may be polygonal, and an end part 9 of the length Le, which is provided with an external thread for fastening the connection element to a junction part of the three-dimensional framework.
To simplify the drawing, the junction part 90 and 'the rod 11 are indicated only by broken lines. In particular, the length Lg may be~ greater than the total of the lengths Lf and Le.
The bolt 5 is guided through the through-bare of a guide sleeve 12, from which the end part 9 projects. At the front part of the guide sleeve ~2 this through-bore is shaped complementally to the guide part 8 of the threaded bolt 5, so that a rotary movement of the guide sleeve 12 can be transmitted to the bolt 5 with as little play as possible.
The through-bore of the front part of the guide sleeve 12 can, therefore, also be polygonal; the same as the guided part of the _8_ ~(~~~fl~
bolt 5. Preferably these cross-sections are hexagonal. In contrast thereto the through-bore has in the rear part of the guide sleeve 12 a preferably round cross-section, in which case there occurs between the round part T of the bolt 5 and the preferably cylindrical inside wall of the guide sleeve 12 a relatively large gap, to form an open space in which a coil spring 13 can be accommodated. At the end of the rear part of the guide sleeve 12, preferably in the gap, an annular disk 14 is arranged and connected to it.
In the shell of the guide sleeve 12 an elongated opening 15 is provided, through which a pin can be loosely inserted and connected to the bolt 5, preferably radially in its guide part 8.
The spring 13 is arranged in the gap in such a way that at its one end it rests on the annular disk 14 and at its other end it rests on the pin 16 to press it forward and thereby push the end part 9 out of the guide sleeve 12, when it is, for example, pushed by hand into the guide sleeve 12. The transmitting of the rotary movement is ensured by the shape of the front part of the guide sleeve 12. On the other hand the pin 16 is provided so that the bolt 5 can be pushed with the fingers along the elongated opening 15 against the action of the spring 13.
The embodiment according to Fig. 1 has the property that the spring 13 remains clamped in the sleeve 12 when this is closed off by the disk 14, e.g. by cementing or welding. It then, therefore, is no longer easy to remove the spring 13 from the sleeve 12. This property is sometimes desirable so that the spring 13 will not get lost. Besides this advantage, the connection element according to Fig. 1 has the disadvantage that the bolt 5 is relatively long. This can be a considerable disadvantage and can be avoided by a round recess 17 on the face of the sleeve head 9. The circumference of this recess 17 must be slightly larger than the circumference of the guide sleeve 12, which on the outside may, for example, have a polygonal cross-section. On the periphery of the sleeve head °1 a recess 18 is provided so that, with the aid of a tool, the sleeve insert 3 can be screwed onto the end of the rod 1'1.
The connection element according to Fig. 2 corresponds essentially to that of Fig. 1, wherein for identical parts the same reference numerals were used: The sleeve 19 according to Fig. 2 has only a small round opening 20, so that after assembling the guide sleeve ~f9 a countersunk pin 21 can be fastened on the bolt 5. Such a design is often preferred when for aesthetic reasons the visible pin is to be dispensed with.
Naturally, in such a case that play between the head of the pin 29 and the round inside wall of the guide sleeve '99 is quite large. As the diameter of the coil spring 13 is well defined and smaller than the projecting part of the pin 21, no slipping of the spring '13 over the head of the pin 2'1 can take place. The diameter of the opening 20 must be slightly larger than the diameter of the pin 29 so that the latter can be pulled out. If need be the opening 20 can be dispensed with, e.g. when the ring '14 is fastened in the sleeve 19 after assembling the spring 13 and the bolt 5.
The connection element according to Fig. 3 corresponds essentially to that of Fig. 'I, and also here the same reference numerals were used for identical parts. With this design the bolt has a radial groove,. which is positioned in the plane perpendicular to the longitudinal axis of the bolt at least approximately in the. area between the smooth part 7 and the guide _5_ part 8. An open annular spring 22 is placed in this groove, the outside diameter of which spring is slightly smaller than the inside diameter of the rear part of a guide sleeve 23, but larger than the diameter of the smooth part 7. The thickness of 'the annular spring 22 may, for example, be smaller than the diameter of the pins 16 or 29 according to Fig. 1 and 2, respectively. In this case the guide sleeve 23 does not have an opening. With this type it is necessary, however, to provide a detachable annular disk which may, for example, be an annular spring that can be clamped into a groove at the end of the sleeve 23.
At the rear end the sleeve 23 has two diametrically opposed openings 26, 27, i.e. in the area where the groove is positioned into which the annular spring 24 can be clamped., so that the latter can be pulled out with the aid of tongues. The openings 26, 27 may be slightly shorter than the height of the recess 17 of the sleeve head 9, so that in the assembled state they remain hidden there. With this type the spring 25 is pressed between the annular springs 22 and 24. The open annular spring 24 could also be used in the connection element according to Fig. 1.
The connection element according to Fig. 4 corresponds to another variant of the type of Fig. 1, wherein for identical parts the same reference numerals were used. In this case, besides the head 6, the bolt comprises only two parts 7 and 9, and the sleeve insert 3 may be with or without a recess 17 tFig. 9). Between the part 9 and the guide sleeve 12, a guide insert 28 is inserted, which has an internal thread and on the outside is shaped complementally to the front part of the through-bore of the guide sleeve '92.
_g_ The through-bore of the front part of the guide sleeve 12 may therefore, also be polygonal, the same as the guided part of the guide insert 28. Preferably, these cross-sections are hexagonal.
In contrast thereto, in the rear part of the guide sleeve 12 the through-bore has a larger, preferably round cross-section, in which case there occurs between the round part 7 of the bolt and the preferably cylindrical inside wall of the guide sleeve 12 a relatively large gap, larger than with the type according to Fig.
1, to form a space in which a conical spring 29 can be accommodated, the diameter of which at the front is smaller than at the rear, so that at the front it presses against the guide insert 28 and at the rear against an annular disk 30 arranged on the end of the guide sleeve 12, the through-bore of which has the same cross-sectional shape and/or is slightly larger than the guide insert 28, so that the latter can be put in through this through-bore. In this case it is easier, after removing the bolt, to take out the spring 29 by pulling and turning it.
The connection element according to Fig. 5 corresponds essentially to the type of Fig, 1, wherein for identical parts the same reference numerals were used. However, with this type at the rear end of the guide sleeve 12 an at least approximately bell-shaped flange ring 31 is provided, which delimits an inside space which is dimensioned such that the head 1 of the sleeve insert 3 can be accommodated therein.
With the embodiment according to Fig. 5 the bell-shaped flange ring 31 is separate from the actual guide sleeve 12, and a bush 32 is provided to fasten the flange ring 31 to the guide sleeve 12, e.g. by screwing or by a bayonet connection. In this case the flange ring 31, the bush 32 and the guide sleeve 12 form a guiding device for the connection element.
The type according to Fig. 5 has the property that the spring no longer remains constantly clamped-in in the sleeve 12, if this is closed off by the bush 32, e.g. by screwing on. The spring 13 can, therefore, easily be removed from the sleeve 12. This property is often desirable so that the spring 13 can be replaced more easily. In addition to this advantage, the connection element of Fig. 5 has the further advantage that due to the bell-shaped flange ring 31 a well matching transition can be realized between the rod 11 and the guide sleeve 12. This type can be made without any opening whatsoever in the shell of the guide sleeve 12, as it can be dismantled very easily.
Instead of the pin 16, a projection of the bolt in the parts 7 and/or 8 may be provided, in which case the opening 15 may also be provided right up to the rear end of the guide sleeve 12.
In a further development of the invention the flange ring 31 may form an integral part with the rear end of the guide sleeve 12.
According to a further development of the invention the flange ring 31 could form an integral part with the bush 28.
In a further embodiment of the invention the bush 32 can fall away and the flange ring 31 may have a wall with a through-bore, the diameter of which is slightly larger than the maximum diameter of the bolt 5.
Finally, the outside of the flange ring 31 may be conical to adapt the larger circumference of the rod 11 to the smaller circumference of the guide sleeve 12.
With the exception of the springs, the other parts may be made from aluminium or another light metal alloy.
_8_ 2~~~~~~
The flange rang 31 and, if it forms an integral part of the sleeve 12 (fig. 5), also the latter may be made from plastic.
The variants of a sleeve with a flange ring explained in connection with Fig. 5 can also be used for other type connection elements.
Finally, it must still be pointed out that instead of a coil spring it is also possible to use a spring that is put on from the side, e.g. a meander-shaped spring, and that with a view to maintaining the tolerances the flange ring andtor the sleeve may also be made from die cast metal, e.g. as bronze or zinc die castings.
